Buffer pedal

I was just pointing out that the TS9 has a buffer so if it was popping, adding another buffer to the front will most likely not fix the problem.

at the risk of making myself sound really stupid, and having followed all your previous threads on pops, what do your "pops" sound like?

perhaps if you record them in action, the experts hereabouts may be able to better target the solutions needed. or redefine your problems.

I found another message about your TS-9. It seems as though there were multiple problems with it. Based on what R.G. said about capacitors and seeing the thread, I would re-check every capacitor and make sure that they are oriented and are of the correct value.

Let me put it this way. This is very similar to "I know I have everything wired correctly. I have checked a thousand times."

Yet the circuit doesn't work.

The answer lies here:

See R.G. "Let's indulge in a bit of basics."

You need to figure it out. It will be a great learning experience and do not rule out user mistakes.

Sounds like a "pop" it is not scratchy or thump...clear pop...


I have done one test with voltage. I have measure a voltage on volume pot of TS9 and readings are: lug 1 and 2 are 4.05 V and lug 3 is 3.97 V...is that good?

I tried to do the same on rebote 2.5. but I cant get readings on pots...are those pedals measured different (it makes no sense but I'll give it a go, probably there are no more stupid questions that I can ask anymore...:-) )...

Well, you need to work on it some more.
If you have to  - buy a working TS9 and figure out why yours pops while theirs doesn't. You will learn a lot in the process. You wanted to know why pops occur - R.G. helped you.

I feel like you already have all the info you need to try and solve your own problem. Now you need to think for yourself and use your own logic to figure out why your circuit is popping. Start with what R.G. said.
Use different capacitors - triple check polarity - measure, measure. Try different guitars/amps.

Finally I have noticed something about your posts. Just because one scenario works - you entirely dismiss the chance that there could still be a problem. For example - simply because your distortion plus works, you assume that everything is fine because that one pedal does not pop. Do not assume anything.
Let's think about this. A normal TS-9 doesn't pop.
so:

1: You have built it correctly - so it's something other than the circuit.
2: You have build it INCORRECTLY - so it's in the circuit. So you have done something incorrectly.  So start fixing the problem! Wrong part - wrong  orientation - bad part. Work on it.

Ok, thanks for helping me. I will try my best to figure thise out and when I find solution I will post my findings here.

Thanks to everyone who helped also. :-)

Hey I wish you luck and please, definitely let us know what you find. I wish you could borrow some pedals (commercial) from others and try and plug them in and see if you get popping even with a commercial pedal. Since you have moved a known good 3PDT (non-popping) to your popping pedal, wow, I guess it's some error on your board.

When I said, don't assume anything - maybe now you need to try and assume that there might be an error on the board itself? I know it's a bought board - but you never know - maybe there's an error??? Maybe you did put things in correctly and there's an error on the board. This will require you to reverse engineer the board - but it will also confirm to you that components are correctly in place. Are you sure you are not measuring DC at the input and output of the pedal???? I would think with the loud popping you hear you would be able to measure it. Again, good luck!
